REGISTER FOR HOT-AIR FURNACES.

Application-filed March 14, 1922.

To all 107mm it may concern: 1

Be it known that I, DANIEL I-IANDELAN, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements inRegisters for Hot-Air Furnaces, of which the follow ing is aspecification.

My invention relates to registers for hot air furnaces. An object is toprovide a reg ister embodying mechanism having a manually operablemember whereby successive impulses may be imparted to cause the registerto move alternately into closed and opened position. Another object isto provide a register embodying a plurality of louvers having pocketsfilled with plastic material to correspond with the ceiling or walls ofthe room provided with the register.

The full objects and advantages of my invention will appear inconnection with the detailed description, and the novel featuresembodied in my inventive idea will be particularly pointed out in theclaims.

In the accompanyng drawings which illustrate the application of myinvention, Fig. 1 is a view of the register in section on the line. 1-1of Fig. 2. Fig. 2 is a view in sec tion on the line 22 of Fig. 1. Fig. 8is a view in section on the line 33 of Fig. 2. Fig. 4 is a view similarto Fig. 3 but showing the register operated into open position. Fig. 5is a fragmentary view in section on the line 5-5 of Fig. 3. Fig. 6 is afragmentary view showing a slight modification, this view correspondingto the similar portion of Fig. 1.

My register is intended for use particularly in connection with overheadhot air furnaces in which the hot air is delivered from a'flue downthrough a register in the ceiling but the register may also be placed inthe side walls of rooms to be heated and may also be used forventilating purposes. As shown in the drawings, a plurality of louvers12 is pivoted at their ends upon pivots 14 attached to a casing 16. Thelouvers consist of metal or other rigid channel members 18, the channelsproviding pockets which are filled with plaster on other plasticmaterial 20. The louvers are connected by a bar 22 which is pivotallyattached to ears 24 mounted on the ends of the louvers. The bar 22 isconnected by a link 26 with a ratchet wheel 28 mounted for rotation upona shaft 29. This shaft Serial No. 543,619.

also has rotatably mounted thereon a pulley V 30 which is provided witha projection 32 to which one end of a spring 34 is attached, the otherend of the spring being attached to the casing 16 so that the springtends to hold the projection 32 in contact with a fixed stop 36. A pawl38 is normally held in engagement with the teeth of the ratchet wheel 28by a spring 40, the latter being secured at one end to the face of thepulley 30 and the pawl being pivotally attached to the face of thepulley. A flexible element 42 is secured at one end to the pulley '30,and this element after extending part way around the pulley and thenthrough an open ing in the ceiling adjacent an end of one of the louversas shown in Fig. 5 is provided at its other end with a ball 44 by meansof which it may be readily pulled. Fig. 4 shows a hot air flue 46connected with the casing 16 for delivering hot air to the register. Theslight modification shown in Fig. 6 is similar to the form already described, the difference being that in this form the louvers instead ofbeing pivotally attached at their middle to the are attached theretoattheir edges by pivots 14 whereby the louvers will be flush with theceiling 0 when in open position as well as when in closed position.

casing 16 The operation and advantages of my invention will be obviousfrom the foregoing description. When thelouvers are in closed positionas shown in Fig. 3, a pull on the flexible element or cord 42 will givethe ratchet wheel and the pulley a half rotation and bring the louversinto opened position as shown in Fig. 4. Upon releasing the cord 42, thespring 34 will immediately return the pulley 30 to its originalposition, the ratchet wheel remaining in the position to which it hasbeen moved. .lVhen it is desired to close the register, the cord isagain pulled, thereby imparting ahalf rotation to the ratchet wheel andpulley and carrying the ratchet wheel around to the position shown inFig. 3. Upon releasing the cord, the pulley will again return tooriginal position. The provision of louvers having pockets filled withplastic material causes the register to present a substantially unbrokencontinuation of the ceiling when the register is closed, since the fineline of separation between the louvers is not particularly noticeable.In case the room is papered, the louvers can be papered over at the sametime and separation of the paper at the edges of the louvers made bycutting through with a knife. My register is well adapted forventilating purposes as well as for use as a hot air register.

I claim:

1. A register for hot air furnaces comprising a plurality of louve-rshaving pocket-s filled with plastic material whereby the reg ister whenclosed presents a substantially unbroken continuation of the adjacentwall surface.

2. A register for hot arr furnaces com prising a plurality of louversconsisting of channel members filled with plastic material 15 DANIELHANDELAN.
